Vinyl Chloride-Vinyl Acetate Copolymer
ANHUI LIWEI CHEMICAL CO.,LIMITED
[Introduction]
Vinyl acetate-vinyl chloride copolymer (PVC) is a widely used material in industrial applications. PVC is a high-strength and flexible plastic because it is made from two distinct chemicals—vinyl acetate and vinyl chloride. This material is heat-resistant, water-resistant, and chemically resistant, making it ideal for custom bed applications. It possesses unique strength and durability.
